People like that are plain sick and should be placed in a padded room. My wife and I and our son used to have magnet ribbons on our vehicles which read "Freedom Isn't Free" Someone stole these ribbons from all of our vehicles. Not because they wanted them for their vehicle, but to stifle our right to express our views. We did get replacements, but have them in our home, rather than take the chance to lose them again. We have placed decals on our vehicles instead. I have a rather large decal which shows a Blue Star on a White Field surounded by a Red Border signifying our son's service. Let them try to steal that one.
Political decals invite vandalism. The American flag and NRA window stickers are the only ones aloowed on my cars.
